Politics
Prior to the Civil Rights Act, Okeechobee County followed the Solid South pattern of voting Democratic, making an exception in 1928 amidst Southern skepticism to Democrat Al Smith's Northern Catholicism. The only non-Republicans to carry Okeechobee County at the presidential level after John F. Kennedy in 1960 were Independent segregationist George Wallace of Alabama (which borders Florida) in 1968 as well as Southern Democrats Jimmy Carter of Georgia (another neighboring state of Florida; 1976 and 1980) and Bill Clinton of Arkansas (1992 and 1996).
Today, Okeechobee County — in line with other Florida Heartland counties — is a rock-ribbed Republican stronghold, with the last Democratic presidential candidate to win the county being Clinton in 1996, the last to be competitive in the county being Al Gore in 2000 (who lost the county by less than 5%), the last to win at least 40% of the county vote being John Kerry in 2004, and the last to win so much as 30% of the vote being Barack Obama in 2012.
